DG407DN Equivalent & Substitute Parts

Part Overview

The DG407DN is a dual 8:1 multiplexer/demultiplexer IC manufactured by Vishay Siliconix, housed in a 28-PLCC surface mount package. This interface component features 100Ohm on-state resistance and operates across a wide supply voltage range of 7.5V to 44V (single supply) or ±5V to ±20V (dual supply). The DG407DN is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitution for the DG407DN is determined by the following critical parameters:

Multiplexer Configuration: 8:1 dual circuit topology
On-State Resistance: 100Ohm maximum (primary electrical characteristic)
Package Compatibility: 28-PLCC (11.51x11.51) surface mount
Operating Temperature Range: -40°C ~ 85°C
Supply Voltage Compatibility: Single supply 7.5V ~ 44V or dual supply ±5V ~ ±20V

Substitute parts must maintain the same circuit topology, package footprint, and core electrical performance within the specified operating conditions. The following parts meet these substitution criteria:

ADG407BPZ: Active product with improved electrical performance (80Ohm on-state resistance, lower charge injection)
DG407DN+: Active product with identical on-state resistance and enhanced specifications
DG407DN+T: Tape & Reel variant of DG407DN+ with identical electrical specifications

Engineering Selection Recommendations

DG407DN+ and DG407DN+T are the primary substitutes for the obsolete DG407DN. Both parts maintain identical on-state resistance (100Ohm), matching channel-to-channel resistance (1.5Ohm), and identical package footprint. These parts are active products with ROHS3 compliance and offer improved electrical characteristics including significantly lower charge injection (2pC versus 15pC) and superior crosstalk performance (-92dB @ 100kHz). DG407DN+T is the Tape & Reel variant suitable for high-volume production environments, while DG407DN+ is supplied in Tube packaging.

ADG407BPZ is an alternative substitute manufactured by Analog Devices Inc. This part features a lower on-state resistance of 80Ohm and improved charge injection (8pC), making it suitable for applications requiring lower insertion loss. However, the supply voltage range is more restricted (12V single supply, ±15V dual supply) compared to the DG407DN's wider operating range. ADG407BPZ is ROHS3 compliant and active.

For new designs and production requiring RoHS compliance, DG407DN+ or DG407DN+T are the recommended selections. For applications with specific low-resistance requirements, ADG407BPZ provides enhanced performance within its specified voltage operating window.

Frequently Asked Questions (FAQ)

Q: Can ADG407BPZ replace DG407DN in all applications?

A: ADG407BPZ is functionally compatible as a dual 8:1 multiplexer in the same 28-PLCC package. However, its supply voltage range (12V single, ±15V dual) is narrower than the DG407DN (7.5V ~ 44V single, ±5V ~ 20V dual). Verify your circuit's supply voltage requirements before substitution.

Q: What is the difference between DG407DN+ and DG407DN+T?

A: Both parts are electrically identical with the same on-state resistance, switching characteristics, and performance specifications. The difference is packaging: DG407DN+ is supplied in Tube format, while DG407DN+T is supplied in Tape & Reel format. Select based on your production volume and assembly process requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. ADG407BPZ, DG407DN+, and DG407DN+T are all ROHS3 compliant. The original DG407DN is RoHS non-compliant, making the active substitutes necessary for applications requiring RoHS certification.

Q: What does the lower charge injection in DG407DN+ mean for my circuit?

A: Charge injection (2pC in DG407DN+ versus 15pC in DG407DN) represents the charge transferred to the output when the switch transitions. Lower charge injection reduces signal distortion and settling time, particularly beneficial in precision analog switching applications.

Q: Is the 28-PLCC package footprint identical across all substitute parts?

A: Yes. All substitute parts use the 28-PLCC (11.51x11.51) J-Lead package with identical footprint and pin configuration, enabling direct PCB layout compatibility.

Q: What is the Moisture Sensitivity Level (MSL) difference between parts?

A: DG407DN and DG407DN+/DG407DN+T have MSL 1 (Unlimited shelf life). ADG407BPZ has MSL 3 (168 hours maximum shelf life after moisture exposure). For long-term storage, DG407DN+ or DG407DN+T are preferred.
